Moongha Invaders Boardgame Miniatures

Here are some plain plastic minis that go with a game called
Moongha Invaders. They're
roughly 28mm scale, and it's a big batch of minis for the price.
The game has two-player battle rules (survivors vs monsters) and
multi-player rules (monsters v monsters v monsters v monsters).

Here is a set of them painted up.

These are the survivors for the two players game. There
are also eight generic "army men" for the multiplayer game.

And the monsters. The game comes with four sets of these in
red, yellow, green, and blue. So with your painting, you
can come up with a color scheme to tell the teams apart in
the multi-player game.
